Text Case Converter

A text case converter changes the capitalisation of any text: UPPERCASE, lowercase, Sentence case, Title Case, slug-case, camelCase and snake_case. It saves time when you fix headings, titles and URLs.

It runs entirely in your browser. Nothing you paste or upload is sent to a server or stored.

How to read the result and act on it

Paste your text and pick the variant you need. Use Title Case or Sentence case for headings and title tags, and the slug version for URLs, which turns spaces into hyphens and removes punctuation. Read the converted text once, because automatic rules can miss proper nouns, acronyms and brand names that should keep their own capitalisation. Copy the result with the button and paste it into your editor or CMS.

Common mistakes to avoid

The typical error is trusting automatic capitalisation for names and acronyms, such as turning iPhone or SEO into something wrong. Another is using uppercase for long text, which is harder to read. Avoid changing the case of URLs that already exist, since that can break links unless you set redirects. Keep slugs short and lowercase.

What is title case?

A style that capitalises the main words of a heading and leaves short words such as of, the and to in lowercase. Style guides differ on the details.

Should URLs be lowercase?

Yes. URLs can be case sensitive, so a consistent lowercase slug avoids duplicate versions of a page.

What is sentence case?

Only the first word and proper nouns are capitalised, like a normal sentence.
